4 Gasketing Selection FACTORS AFFECTING GASKET PERFORMANCE A gasket has one basic function: to create a positive seal between two relatively stationary parts. The gasket must do a number of different jobs well to function properly: first, create an initial seal; second, maintain the seal over a desired length of time; third, be easily removed and replaced. Varying degrees of success are dependent on how well the gasket does the following: 1. Seals system fluid. 2. Chemically resists the system fluid to prevent serious impairment of its physical properties. 3. Deforms enough to flow into the imperfections on the gasket seating surfaces to provide intimate contact between the gasket and the seating surfaces. 4. Withstands system temperatures without serious impairment of its performance properties. 5. Is resilient and resists creep enough to maintain an adequate portion of the applied load. 6. Has sufficient strength to resist crushing under the applied load, and maintain its integrity when being handled and installed. 7. Does not contaminate the system fluid. 8. Does not promote corrosion of the gasket seating surfaces. 9. Is easily and cleanly removable at the time of replacement. During the gasket product selection process that follows, we recommend that these nine (9) factors be used as a checklist from the viewpoint of the user s degree of need for each factor and the manufacturer s degree of compliance. Selecting gasketing materials for particular applications is not an easy task. The variables present in a flanged connection seem endless and yet all of them must be taken into consideration to assure a proper seal. In the past, the acronym "TAMP" (Temperature, Application, Media and Pressure) seemed to give sufficient information to make a gasketing recommendation. Today, items such as: the flange material, the bolt grade, the flange surface finish (and many other variables) also affect how well a gasket will perform. In addition, the definition of what a seal is has changed drastically over the years. Leakage measurements in some applications have gone from drips a minute to parts per million. Our catalog is designed to help guide you through the various gasketing products and narrow your choices. All industry standard tests are included in order to allow an end user a means of comparison between different materials. Many of the test procedures require that the tests be conducted on 1/32" material. As a rule of thumb, gasket performance decreases as material thickness increases. In addition, compressive loads must be increased with thicker materials. Proper bolting sequences are necessary to ensure those compressive loads are uniform. The temperature, pressure and P x T ratings are all based on optimum conditions. When approaching those extremes, it is suggested that you consult with the Garlock Applications Engineering Department or possibly upgrade to a material that has higher ratings. As industry standards change and new products are introduced, this catalog will be updated. In the meantime, we urge you to take advantage of our experienced personnel for assistance. In-plant training, instructional videos, additional technical information and gasketing recommendations all are available to help in your selection process. Please feel free to call, fax, write, or us should you have any questions or concerns. Garlock is here to help. Selection thought process: There is a thought process required when selecting a gasket; it basically involves narrowing the choices as we learn the requirements and service conditions. While many people are familiar with the need to know the temperature, media, and pressure, few realize how important it is to fully understand the application, which can be thought of as the mechanical situation the gasket will see. First and foremost is the compressive load applied to the gasket. With standard flanges, such as 150# raised face (RF), we know the range of compressive load on the gasket. With non-standard flanges, we require more information. While not quite as simple as this, a way to begin this thought process is this: Rubber and some of the softer materials are preferred in light weight and/or full face/flat face flanges; fiber and GYLON gaskets for 150# RF flanges; Flexseal spirals or Kammprofile gaskets for high temp/ high pressure/high compressive load situations. We then consider temperature, pressure and media to select a material. 4

5 Gasketing Selection & TAMPS TEMPERATURE In most selection processes, the temperature of the fluid at the gasketed joint should be considered first. This will reduce the number of product candidates quickly, especially as temperatures go from 200 F (95 C) to 1,000 F (540 C). When system operating temperatures approach a particular gasket material s maximum continuous operating temperature limit, an upgrade to a superior material is suggested. In some situations cryogenic temperatures must also be considered. APPLICATION The most important information under application is the type of flange and bolts used. The number, size and grade of bolts, along with the flange thickness and material, determine the load available. The surface area being compressed is calculated from the gasket contact dimensions. The load from the bolts and the contact area of the gasket result in the compressive load available to seal the gasket. We have calculated and tabulated this information on standard ANSI raised face flanges (see page 51). The compressive stress available on nonstandard flanges must be calculated on an individual basis. Without this information, we cannot choose between various types of materials such as elastomeric (rubber) gaskets, compressed sheet, GRAPH-LOCK and GYLON styles. For example, nonmetallic flanges such as FRP and CPVC are mostly designed for rubber gaskets. They typically use a full face gasket, and the allowable torque is limited so that the flanges do not crack when bolted. Flat faced flanges made from cast iron, aluminum, bronze, or light weight angle iron or plate will also use a full face gasket to avoid bending forces in the flanges. We try to use softer gaskets in these as well, although fiber gaskets and GRAPH-LOCK will often work. Flanges that create very high compressive loads might require a metallic spiral wound or kammprofile, but many can also be sealed with a fiber or GYLON gasket. A 150# RF flange is fine with any of these; a 600# RF flange is best suited for a metal gasket. MEDIA There are thousands of different fluids. We cannot, in this manual, make recommendations for all fluids. Fortunately, however, there are a relatively limited number of fluids that make up the vast majority of the media encountered in industry. A general overview of fluid compatibility is provided for the most popular styles shown in this manual (see Chemical Resistance chart, pages 27-44). System clean out and flushes should also be considered. Additional information on products versus fluids is available upon request. PRESSURE Next to be considered is the internal pressure of the fluid at the gasketed joint. We list the maximum pressure limits for each style. If severe and frequent pressure changes are involved, we should be given the details, since an alternative product may be needed. SPECIAL REQUIREMENTS In addition to the TAMPS, there are other requirements that are IN ADDITION to the information listed above. Examples are compliance with FDA, fire resistance, electrically insulating properties, cleaned for oxygen service, etc. We have the words IN ADDITION in caps because it is not uncommon to be asked for a fire resistant gasket or an FDA gasket, without the necessary TAMP information. PRESSURE (PSIG OR BARG) X TEMPERATURE ( F OR C) We strongly recommend that pressure and temperature be considered simultaneously by using the following procedure: 1. First select the Garlock style(s) being considered for your application/service, 2. List the maximum pressure, temperature and P x T value for the style(s), 3. Make sure the actual service conditions do not exceed the style limitations in any of the three criteria. If they don t, the style(s) can be used, provided all other requirements are met. If they do exceed any one limit, another style or styles should be considered. Rarely can a style be recommended when the service conditions of pressure and temperature are both at the maximum limits for that style. Example: BLUE-GARD Compressed Gasketing Style Pressure Limit: 1,000 psig (70 bar) 2. Maximum Temperature Limit: 700 F (370 C); Continuous Operating Temp.: 400 F (205 C) 3. P x T Limit: 350,000* (12,000) At 1,000 psig (70 bar), maximum temperature is 350 F (180 C). IMPORTANT Maximum pressure and P x T ratings are based on the use of ANSI RF flanges at our preferred torque. The ratings were developed using laboratory tests at ideal gasketing conditions. Field conditions will undoubtedly affect the gasket performance. When approaching maximum pressure, continuous operating temperature, minimum temperature or 50% of maximum PxT, consult Garlock Applications Engineering. We hasten to point out that this method for gasket selection is merely a general guide and should not be the sole means for selecting or rejecting a product. * P x T based on 1/16" sheet thickness unless otherwise stated. 5

6 Bolting and Flange Information The gasket s function is to seal two different surfaces held together by one of several means, the most common being screw-threaded devices such as bolts. Sometimes the fastener itself must be sealed, as in the case of a steel drum bung. The bolt is a spring. It is an elastic member that has been stretched to develop a load. The more spring provided by the bolt, the better the retention of stress on the gasket to maintain a leakproof joint. It must not be over-elongated (over-strained), or the elastic limit of the steel will be exceeded. The bolt then deforms and, with continued loading (stressing), may break. PROPER TIGHTENING To avoid such problems with bolt tightening, the use of a torque wrench is recommended. The torque tables on page 50 show the recommended torque values for Garlock compressed sheet, GYLON and GRAPH-LOCK gasketing materials in 150 lb. and 300 lb. raised face flanges. The equipment designer may specify the recommended torque to prevent damage to the equipment from over torquing. Garlock s recommended assembly stresses, page 49, may help the equipment designer determine the maximum allowable torque per bolt. The load will be retained better by using a bolt with a longer grip, thereby ensuring a leakproof joint. IMPERFECTIONS There are limits on the degree of flange surface imperfection that can be sealed successfully with a gasket. Large nicks, dents, or gouges must be avoided, since a gasket cannot properly seal against them. The surface finish of a flange is described as follows: 1. Roughness: Roughness is read in millionths of an inch (or meter) as the average of the peaks and valleys measured from a midline of the flange surface. This is expressed either as rms (root mean square) or AA (arithmetic average). The difference between these two methods of reading is so small that they may be used interchangeably. Roughness is also expressed as AARH (arithmetic average roughness height). 2. Lay: Lay is the direction of the predominant surface-roughness pattern. Example: multidirectional, phonographic spiral serrations, etc. 3. Waviness: Waviness is measured in thousandths or fractions of an inch. Basically, it is the departure from overall flatness. FLANGE FINISH Typical roughness readings can be from 125 to 500 micro-inches for serrated flanges and micro-inches for non-serrated flanges. Fine finishes, such as polished surfaces, should be avoided. Adequate "bite" in the surface is required to develop enough friction to prevent the gasket from being blown out or from extruding or creeping excessively. SERRATIONS OR ROUGHNESS The lay of the finish should follow the midline of the gasket if possible. Take, for example, concentric circles on a round flange, or a phonographic spiral. Every effort should be made to avoid lines across the face, such as linear surface grinding, which at 180 points will cross the seal area at right angles to the gasket, allowing a direct leak path. Waviness is seldom a problem under normal conditions. There are two areas that must be watched, however, since excessive waviness is very difficult to handle. The first area is glass-lined equipment where the natural flow of the fused glass creates extreme waviness. Often the answer here is to use thick and highly compressible gasketing. The second area of concern is warped flanges. If warpage is caused by heat or internal stresses, re-machining is generally sufficient. However, warpage due to excessive bolt loads or insufficient flange thickness results in what is generally called bowing. The solution is to redesign for greater flange rigidity. Sometimes backer plates can be added to strengthen the design without having to replace the parts. Another step would be to add more bolts. When this is done, usually smaller bolt diameters are possible, thus adding more bolt stretch and better joint performance. 6

There have been conflicting field reports concerning the suitability of NBR and neoprene bound gaskets in 123. End users should take note. 4. Style 5507 is rated A. 5. Some chromium plating baths contain fluorides that can attack silica and silicate type fillers in some GYLON styles. If the bath is known to contain little or no fluoride, all GYLON styles should be suitable for use. 6. These GYLON styles can be expected to be suitable to 60% concentration at temperatures up to 250 F (121 C). 7. Use GYLON styles 3502, 3503, 3505, 3562, These styles are specially processed, cleaned and packaged for oxygen service. 8. This GYLON contains a stainless steel insert. There is a possibility that this might contribute traces of iron to form iron tannates, resulting in undesirable color in the tannic acid. 9. These styles are not preferred choices for steam service, but are successful when adequately compressed. 10. If a gasketing material that conforms to FDA requirements is desired, contact factory for specific recommendations. 11. These GYLON gasket styles can be expected to be suitable to 75% concentration at temperatures up to 400 F (204 C). 12. Minimum recommended assembly stress = 4,800psi. Preferred assembly stress = 6,000-10,000psi. Gasket thickness of 1/16 strongly preferred. For saturated steam above 150psig, consult Garlock Engineering. 13.

48 Before Installation Installation Remove old gasket, and clean flange surface of all debris. For best results, use a soft metal flange scraper, an aerosol gasket remover and a soft wire brush, then inspect the flange for damage. Be sure surface finish and flatness are satisfactory. Use the thinnest possible gasket. However, flanges that are warped, bowed or severely pitted require thicker gaskets. It is best to install gaskets as received. On compressed fiber gaskets, if additional release agents are needed, dry is better than wet. Never use metal based anti-seize, since particles may accumulate in the surface imperfections, thereby creating a flange surface that is too smooth to be effective Center the gasket on the flange. This is extremely vital where raised faces are involved. NOTE: Standard ANSI ring gaskets, when properly cut, should center themselves when the bolts are in place. Fasteners must be new or "as new" condition Use of a torque wrench and well-lubricated fasteners with hardened flat washers is essential to ensure correct initial loading. Tighten bolts to compress gasket uniformly. This means going from side to side around the joint in a star-like crossing pattern. See diagrams on left. Starting with all fasteners "snug", bolts should be tightened in onethird increments, according to proper bolting patterns. Retorque 12 to 24 hours after start-up, whenever possible. All applicable safety standards including lockout/tagout procedure should be observed. Never use liquid or metallic based anti-stick or lubricating compounds on the gaskets. Premature failure could occur as a result. Circular Four-Bolt Noncircular Multibolt Square Four-Bolt Circular Multibolt Gasket Assembly Stress Recommendations 48 The minimum recommended assembly stress for Garlock compressed sheet such as BLUE-GARD, GYLON and GRAPH-LOCK products differs from "M" and "Y" values. "M" and "Y" do not take factors such as flange condition and blowout resistance into account. Garlock offers the following minimum assembly stresses as rules of thumb for calculating installation bolt torques. Operating Pressure in psig (bar) Minimum Assembly Stress Recommended psi (N/mm 2 ) 1/32" (0.8mm) Thick 1/16" (1.6mm) Thick 1/8" (3.2mm) Thick Up to 300 (21) 2,500 (17) 3,600 (25) 4,800 (33) Up to 800 (55) 4,800 (33) 5,400 (37) 6,400 (44) Up to 2,000 (140) 7,400 (51) 8,400 (58) 9,400 (65) FLAT FACE FLANGES Minimum recommended gasket stress for GYLON and Compressed Fiber gaskets in full face/flat faced flanges can be much lower. Stresses in the range of 1000 to 2000 psi are usually acceptable for liquid services. Please contact Applications Engineering when using these materials as full face gaskets in flat faced flanges, especially when dealing with gaseous media. Maximum recommended compressive stress for: Compressed fiber and GYLON gaskets = 15,000 psi Multi-Swell Style 3760 = 10,000 psi GRAPH-LOCK gaskets = 10,000 psi Recommended compressive stress for: STRESS SAVER gaskets = 600-1,200 psi Rubber gaskets to 60 duro = psi Rubber gaskets to 70 duro and higher = 600-1,200 psi * Maximum stresses assume standard ASME serrated flanges at micro-inch flange finish.

See also Flanges on page Contact Garlock Applications Engineering at for further discussions regarding the use of compressed, GYLON or GRAPH-LOCK products in flat face flanges. 4 For full face GYLON, compressed sheet and GRAPH-LOCK gasketing, 1,000 to 2,000 psi is normally acceptable for installation. 52

54 Gasket Design Tips PROBLEM RESULT SUGGESTED SOLUTIONS Bolt holes close to the edge. Causes breakage in stripping and assembling. Projection or "ear". Very small bolt holes or non-circular openings. Require handpicking... easy to miss. Avoid hole sizes under 3/32" diameter. If small hole is for locating or indexing, change to notch. Tear-away parts with open slots at attached edges. Slots require handpicking, costly dies and die maintenance. Simple perforation. Thin walls, delicate cross-section in relation to overall size. High scrap loss; stretching or distortion in shipment or use. Restricts choice to high tensile strength materials. Have the gasket in mind during early design stages. Metalworking tolerances applied to gasket thickness, diameters, length, width, etc. ± Results in perfectly usable parts being rejected at incoming inspection. Requires time & correspondence to reach agreement on practical limits. Increases cost of parts and tooling. Delays delivery. Most gasket materials are compressible. Many are affected by humidity changes. Try standard or commercial tolerances before concluding that special accuracy is required. Transference of fillets, radii, etc. from mating metal parts to gasket. Unless part is molded, such features mean extra operations and higher cost. Most gasket stocks will conform to mating parts without pre-shaping. Be sure radii, chamfers, etc., are functional, not merely copied from metal members. Large gaskets made in sections with beveled joints. Extra operations to skive or glue. Difficult to obtain smooth, even joints without steps or transverse grooves. Die-cut dovetailed joint. 54

55 Gasket Terms 3A GYLON Style 3522 is 3A compliant. For documentation, please contact Garlock Applications Engineering. AMERICAN BUREAU OF SHIPPING Garlock styles on the American Bureau of Shipping Type Approval program: BLUE-GARD 3000, * GRAPH-LOCK 3125SS, 3125TC 3128 GYLON 3500, 3504, * ** THERMa-PUR ANTI-STICK While we prefer that gaskets be installed with only the factory-applied anti-stick, experience shows that additional anti-stick is helpful in some situations, such as areas where flanges cannot be separated easily. Coatings should be as light as possible. Dry powders are strongly recommended over pastes and grease-type compounds, which can drastically reduce the crush strength and blowout resistance of the gasket. Additionally, grease or paste type materials may deteriorate or dissolve in service, leaving a possible leak path across the gasket. AVIATION GASOLINE Gasoline with a high octane number is used for prop driven airplane engines, as opposed to jet fuel for jet engines. Aviation gasoline contains a high percentage of aromatics. GYLON is preferred; compressed sheet styles with nitrile binders can be successful in some applications (see Jet Fuel). Consult Engineering if you are unsure. BUBBLE TESTS Some end users perform bubble tests of their system to check gasket tightness. This information is helpful before specifying a gasket. Bubble tests are an extremely tough test for a gasketed joint, and may not be an appropriate means to verify correct installation. Lightweight flanges with low available compressive load may never achieve "bubble tight" results. CHLORINE SERVICE We recommend our GYLON styles for chlorine. The style selection is made based on flange information. Style 3510 is listed in the Chlorine Institute s Pamphlet 95. Garlock Metallic Gasket Division products are also listed, including the GRAPHONIC gasket. NOTES: * Accepted for use where "fire safe" requirements are specified by ABS rules and US Coast Guard regulations ** Non-stocked item CLOTH INSERTED (CI) RUBBER Most CI rubber styles are designed for use as diaphragms, not gaskets. While CI rubber is more crush resistant than unreinforced rubber, customers have reported media "wicking" or leaking through the insert over time. COMPRESSION The amount of compression expected on a particular gasket type depends on its compressibility data and the load applied. Sealing problems are often a result of lack of compression. Graphs of compression vs. Ioad on popular gasketing styles are available upon request. Close tolerance sheet should be considered for applications requiring tight internal clearances such as split case pumps (see Modulus of Elasticity). COMPRESSIVE STRESS Undercompression: Underloaded gaskets will have higher leak rates and lower blowout resistance than properly loaded gaskets. This has a profound effect on performance and is the most frequent cause of joint problems. Overcompression: Overcompression can lead to crushing, which accelerates the degradation of the gasket and can even cause immediate failure. Uneven Compression: Gaskets resist blowout based on the friction of the gasket against the flange. The higher the compressive load, both initially and during service, the higher the blowout resistance. When areas of high and low compression exist in a flange joint, the areas of low compression are prime candidates for blowout. CREEP RELAXATION A term used to describe the loss of bolt load over time which typically increases with temperature and gasket thickness. CRUSH STRENGTH Garlock recommends a maximum compressive stress of 15,000 psi on compressed fiber and GYLON gasketing, and 10,000 psi on GRAPH- LOCK and Multi-Swell gasketing. The actual crush strength of these materials is typically higher. CRYOGENIC SERVICE We recommend our GYLON styles down to -450 F (-268 C), and our compressed sheet gasketing is typically recommended to -100 F (-75 C). DIELECTRIC BREAKDOWN VOLTAGE Many applications require a gasket which is not a good conductor of electricity. Garlock has dielectric breakdown voltage test data available on our most popular gasketing styles. Generally speaking, GYLON styles and compressed sheet that does not use carbon or graphite fibers have high dielectric breakdown values. Under humid or wet conditions, Styles 3504 and 3565 are particularly resistant to dielectric breakdown. 55

56 Gasket Terms EMISSIONS There is certainly a great deal of interest in limiting emissions of the numerous chemicals and other substances regulated under the Clean Air Act. Garlock has performed testing in this area and our report, available on request, covers the effects of gasket type, compressive load, internal pressure and flange finish on relative emissions levels. The use of heavier flanges where possible and the selection of premium gasket materials with good sealability numbers are the easiest ways to reduce emissions. FDA Style 3500 (Fawn) and Style 3510 (Off-White) comply with FDA regulation 21CFR They meet ingredient and extract requirements. The fillers are also acceptable under 21CFR and coloring agents (where used) under 21CFR Style 3500 (Fawn) has USDA approval for direct contact in meat and poultry applications. Style 3504 (Blue) and Style 3565 (ENVELON ) comply with FDA regulation 21CFR They meet the ingredient and extract requirements. The filler is listed in the Food Chemicals Codex (FCC 3rd Edition) and is considered GRAS (generally recognized as safe 21CFR170.30). Style 3522 (Clear) complies with FDA regulation 21CFR The ingredients for Style 3540 (Microcellular) and Style 3545 (Microcellular with Rigid Core) comply with FDA regulations 21CFR , 21CFR182.1, 21CFR , and 21CFR The PTFE resins used in Style 3535 PTFE joint sealant comply with FDA regulation 21CFR The PSA tape used to hold the joint sealant material in place meets 21CFR FIRE TESTS Garlock previously used a Fire Test Standard modeled after industry fire tests API 589 and 607. Styles 9900, 9800, 9850, IFG 5500 and GRAPH- LOCK styles have all passed this fire test. Recent testing performed at third party facilities. Test procedures and results are available upon request. FLANGES Flanges come in all shapes and sizes, and the type of flange used in a service has a large impact on the type of gasketing material recommended. Standard ANSI raised face flanges are best suited for use with compressed fiber and GYLON gaskets. Elastomer (rubber) gaskets may be crushed in these flanges. Flat faced non-metallic flanges seal best with elastomeric (rubber) gaskets, such as the various STRESS SAVER gasket styles. GYLON Style 3545 may also be suitable for some applications. Compressed fiber and standard GYLON are frequently used in flat-faced carbon steel flanges, but the compressive stress available in these flanges is well below our minimums. The result is that the gaskets are compressed very little; if there is a significant flange irregularity present, the gasket may not seal. Since leakage rates of gaskets depend on the available compressive stress, the joint may not be as tight as the customer would like. FLANGES CONT. Glass-lined flanges are found in many chemical applications. Due to the inherent "waviness" created when these flanges are fired to apply the glass, the softer GYLON styles such as Styles 3545, 3565, and 3504 are preferred. The gap between the flanges, when placed together empty, must be measured before the gasket is ordered. Gasket thickness should be four to five times the maximum gap observed. Stainless steel (SS) flanges are common in many plants for chemical service, and often utilize low strength SS bolts. Due to the chemicals present and the low compressive stress generated by the bolts, Styles 3545, 3565, and 3504 are often recommended. We do prefer, however, the use of high strength, strain-hardened stainless steel bolts. Styles 3000, and Stress Saver XP are the preferred choices in water service in stainless steel flanges, due to their very low leachable chlorides. Consult Garlock Engineering when considering other styles. See Stress Saver XP, catalog page 20. FLANGE FINISH We recommend the flange finish conform, whenever possible, to serrations per inch, in a concentric or spiral pattern, cut with a 1/16" radius, round-nosed tool. This finish is usually difficult or impossible to create in non-circular flanges. We recommend that machined surfaces which can not be serrated have a surface finish with a multi-directional lay and roughness of micro-inch RMS. FUEL ADDITIVES The chemical MTBE (methyl t-butyl ether) has become a very common fuel additive and gasketing compatibility inquiries on this material are frequent. Garlock in-house testing has shown GYLON gasketing to be unaffected by MTBE. We have also found compressed sheet Styles 9850 and 3000 to be suitable for MTBE service. These materials are recommended for MTBE alone or mixed with gasoline. F104 LINE CALLOUTS These designations are not intended to be used as specification limits; intended for generic description of physical properties. FULL FACE GASKETS See Flanges. GASKET CONSTANTS The ASME and ASTM committees are working on a new system and new set of numbers to be used in the ASME code calculations for flange design. These new constants address leak rates at installation and during loss of compressive load and therefore are meant to help end users design for a certain leak level. The use of a defined leak rate will often generate higher bolt load requirements for the flanges, which should improve performance of designed joints. For gasket constant values, see page 47. Also see M & Y Values and Emissions. 56

57 Gasket Terms GASKET IN GROOVES OR RECESSED FLANGES Gaskets installed in grooves or tongue and groove flanges require one extra consideration: the compressed height of the gasket must be considered. This is typically important where a highly compressible gasket such as GYLON Styles 3545 and 3540 or one of the GRAPH- LOCK styles is used to replace a compressed sheet gasket. The fully compressed thickness, not the original thickness, must be greater than the groove depth or the space between the tongue and groove when flanges contact each other. Ideally, the tongue should be at least as tall as the groove depth. GASOHOL Gasohol is a blend of gasoline with an alcohol usually 10-15% ethyl alcohol. GYLON styles are preferred; nitrile-bound compressed sheet styles should be acceptable; most rubber gaskets are not recommended. INSTALLATION Garlock strongly recommends the use of calibrated torque wrenches to tighten bolts to the correct load. We have an installation procedure and discussion available upon request. A video covering the same material is also available. INSULATION KITS (PIKOTEK ) Customers will occasionally ask for a flange insulation or isolation kit or gasket to electrically insulate one flange from the mating flange. Kits are available from the GPT division as well as a variety of distributors and include an insulating gasket along with a sleeve for the bolts and insulating washer to be installed under the steel washers and nuts. (see Dielectric Breakdown Voltage). JET FUELS Most jet fuels are typically refined petroleum products similar to kerosene. We recommend our GYLON, nitrile bound compressed sheet and GRAPH-LOCK products. (See Aviation Gasoline) For JP9 or JP10, please contact Applications Engineering. LEACHABLE LEVELS (CHEMICAL) Some pipe specifications call out maximum levels of "leachables" for gaskets. These limits are usually concerned with leachable chlorides, fluorides, halogens and sulfur. These ions, or charged particles, are of concern due to their tendency to promote corrosion of piping systems. Garlock keeps test results for numerous gasket styles on file and we will test and certify leachable chlorides, etc., where required. There is a charge for these tests. "M" AND "Y" VALUES FOR FLANGE DESIGN See page 46. NOTE: Our testing shows an increase in "M" and "Y" values as gasket thickness increases. This is the opposite of the trend found in the ASME Code. Fugitive emission and gasket blowout studies have validated this trend. MILITARY SPECIFICATIONS Due to the variation of the certification and specification requirements, a manual review must be performed on each inquiry or order to verify certification and specification demands and to ensure the order is processed to meet the needs of the requestor. Certification and specification charges will vary with the number of sheets due to the number of batches required to complete the order. Garlock has three gasketing products that meet Navy specifications. Garlock Style 3125SS is specified for MIL-DTL Type I, Style 3200 is specified for MIL-DTL Type II and Style 9900 is specified for STR-508. Ordinarily the products are certified prior to sale to the Navy or shipyards. Testing charges apply. MODULUS OF ELASTICITY Some flange programs ask for the modulus of elasticity for the gasket material. Since only rubber gaskets are elastic the other types of gasketing do not have a true modulus. However, Garlock Applications Engineering does have compression vs. Ioad curves which can be used to calculate a rough estimate for use in these calculations (see Compression). MONOMERS Monomers are materials, such as styrene and vinyl chloride, which can combine with themselves and become polymers, such as polystyrene and polyvinyl chloride. GYLON Styles 3510 and 3530 are recommended for monomers, since elastomer-bound gaskets are rarely compatible with monomers. Some monomers, under certain conditions, will penetrate a gasket and polymerize inside the gasket, causing the gasket to swell and, occasionally, rupture. This effect is known as "popcorning". This effect can be reduced or eliminated with additional compressive load which lowers the void space inherent in a gasket. NSF 61 FOR DRINKING WATER Current approved styles include 3760-U, 3505, 3505 STRESS SAVERS, XP STRESS SAVERS and EPDM style OXIDIZERS Certain chemicals are known as strong oxidizers and, as such, will readily combine with organic compounds. We recommend our GYLON material for use in oxidizers. OXYGEN SERVICE We recommend GYLON Styles 3502, 3505, 3503 and metal-inserted Styles 3562 and These gaskets are specially manufactured and packaged to eliminate contamination by organic material. GRAPH- LOCK Styles 3123 (1/16" thick max) and 3128 HOCHDRUCK are also acceptable. 57

58 Gasket Terms ph The ph scale is a measure of the acidity or alkalinity of a solution. A ph of 7 is a neutral reading; it is neither acidic or alkaline. Readings of 1-2 are strongly acidic, while indicates a strong alkaline or caustic media. Note: A ph reading alone without the names of the chemicals involved is not enough to select a gasket. Also, since the ph scale is quite limited in range, a reading of "1" or "14" does not fully describe the concentration. We need the concentration expressed as a percentage. For example, sodium hydroxide at a concentration of around 4% will "peg" the ph scale at 14, the same reading produced by a 40% concentration. PRESSURE SPIKES Very high pressure spikes can occur in any line pumping a liquid if a valve is closed rapidly, leaving the fluid flow nowhere to go. The inertia of the fluid may create extreme pressure spikes. These spikes occur too rapidly to be detected by a pressure gage but can cause a gasket to blow out. RADIATION RESISTANCE We have conducted gamma radiation tests on our compressed sheet Styles 3000, 3200, 3400, 3700, 5500, 5507, 9800, 9850, These tests indicate our compressed styles will handle a total exposure of approximately 5 x 10 7 rads of gamma radiation. GYLON Styles 3510 and 3545 have been tested. Test results are available. REFRIGERANTS Refer to the Chemical Resistance chart for a complete listing of refrigerants. Gaskets with a "B" rating are usually acceptable in refrigerants. The compatibility of the lubricants used with these refrigerants is rarely an issue with fiber gaskets. REUSE OF GASKETS We are frequently asked about reusing a gasket. We do not recommend this practice. A gasket s function is to conform to flange high and low spots when compressed, and its ability to reseal decreases after it is compressed. Gaskets which contain rubber and which have experienced elevated temperatures will be even less likely to reseal. SHELF LIFE Garlock has spec sheets detailing proper storage conditions and expected shelf life for our products. Available upon request. SPACERS IN FLANGES Some installations require a very thick gasket to fill a large gap between flanges. We do not recommend stacking numerous gaskets in the same flange. In-house tests have shown that a better way to fill a 1/2" gap, for example, is to install a 1/16" gasket on each side of a 3/8" thick incompressible spacer ring. Ideally, the spacer ring will be consistent with piping metallurgy, serrated, and cut to the same dimensions as the gasket. We recommend higher minimum torques when using this arrangement. STEAM Steam can be found in plants in two forms: saturated and superheated. Saturated steam is standard boiler steam and has a definite temperature for each pressure. Superheated steam is steam at a higher temperature than is found on the saturated steam curve for that particular pressure. We recommend our GRAPH-LOCK styles or graphite/metal gaskets for superheated steam. Please consult with Garlock Engineering when steam pressure exceeds 150 psig. Also see notes on steam service found on fiber gasket specification pages. THERMAL CONDUCTIVITY Values available from Applications Engineering. THICKNESS, GASKET Garlock recommends the use of thinner gaskets wherever possible. This not only lowers the cost of the gasket, it increases the performance of the joint by lowering emissions and product loss and increasing blowout resistance. Thinner gaskets will not seal as many flange irregularities as thicker gaskets, however, and require flatter flanges. Experience with the particular flange system is often an important guide when specifying a gasket thickness. A more complete discussion of the subject is available. TORQUES, BOLT We realize many end users resist using a torque wrench for installation. We have found the use of a torque wrench to be the least painful way to gain a substantial increase in performance. Any method which accurately controls the compressive load on the gasket is acceptable. See Bolt Torque Tables for ANSI/ASME B16.5 RF flanges on page 49. For non-standard flanges, contact Applications Engineering. The maximum torque values for flanges such as glass-lined or PTFE-lined, FRP and PVC-type flanges are established by the flange manufacturer to avoid damage to the flanges. We recommend the use of the maximum allowable torque for each size. These maximum torques are usually lower, and often much lower, than we would recommend. TRACED LINES (HEAT TRACED) Heat traced lines pumping materials which are solid at ambient temperature can present a number of problems for gaskets: 1. The bolts are usually hotter than the flanges since the heat is applied from outside the pipe. This causes the bolts to expand more than the pipe, which lowers the compressive stress on the gasket. 2. Any line which is shut down will freeze solid. When the line is reheated on start-up, there is occasionally a plug of solid material blocking a section of the pipe. The heating may cause some areas of the material to liquefy and then expand. The expansion can create extremely high pressures inside the joint if the solid plug is blocking a section of the line. 58

59 Gasket Terms USDA See FDA. USP (UNITED STATES PHARMACOPEIA) GYLON Style 3500, 3504, 3510 and 3522 are USP Class VI approved. For documentation, please contact Garlock Applications Engineering. VACUUM Most Garlock gaskets can seal well in vacuum, even full vacuum. The challenge is when flanges are designed with too little bolting. A more complete discussion is available from Application Engineering as well as guidance on specific recommendations. Flange and bolting information will be required. 59

60 Test Procedures BLOWOUT OF GASKET PRODUCTS (No ASTM Designation) Garlock developed the equipment and test procedure used for testing the blowout resistance of gaskets at varying pressures and temperatures. This test method and procedure enable us to compare the blowout resistance of all types of non-metallic gasketing products. The test fluid is nitrogen gas. Internal pressures can be varied from atmospheric to approximately 5,000 psig (345 bar). The flanges and gaskets can be exposed to temperatures up to 1,000 F (540 C). Garlock blowout tests are primarily used to compare various products, and do not represent results that can be expected under actual field conditions. The experience gained over many years in blowout testing provides part of the technical backup of our data on longer term P (psig or bar) x T ( F or C) values. COMPRESSIBILITY AND RECOVERY OF GASKET MATERIAL ASTM Designation: F36 This method covers determination of the short-time compressibility and recovery at room temperature of sheet gasket materials. This test method is not intended as a test for compressibility under prolonged stress applications, generally referred to as "creep", or for recovery following such prolonged stress applications, the inverse of which is generally referred to as "compression set". Some initial compressibility is essential for proper installation of a gasket and is required to compensate for any flange irregularities such as minor flaws or nicks, non-parallelism, corrosion and variations in groove depth. Voids must be filled to obtain proper seating of the gasket or premature failure will occur. In addition, good recovery upon release of load is indicative of torque retention of a gasketed joint. Compressibility and recovery as defined by ASTM are two worthwhile physical property criteria for supplier and purchaser to agree upon as routine tests. CREEP RELAXATION OF GASKET MATERIAL ASTM Designation: F38 Method B Measured by means of a calibrated bolt with dial indicator, ASTM F38 provides a means for measuring the amount of creep relaxation of a gasket material at a stated time after a compressive stress has been applied. There is no fluid involved. This method is designed to compare related products under controlled conditions in regard to their ability to maintain a given compressive stress as a function of time. A portion of the torque loss on the bolted flange is a result of creep relaxation. Creep relaxation is defined by ASTM as: "A transient stress-strain condition in which the strain increases concurrently with the decay of stress." The result of creep relaxation is loss of thickness of a gasket, which causes bolt torque loss, resulting in leakage. Torque loss also can be caused by elongation of bolts, flange distortion and vibration. Therefore, results obtained in lab conditions should be correlated with field results. Also see Torque Retention Test for further information. FLUID RESISTANCE OF GASKET MATERIALS ASTM Designation: F146 These methods provide a standardized procedure for measuring the effect of immersion on physical properties of non-metallic gasketing materials in specified fluids under defined conditions of time and temperature. The types of materials covered are those included in the first numeral described in Classification F104. They are not applicable to the testing of vulcanized rubber, a method described in Test Method D471. The test fluids and conditions outlined were selected as typical for the purposes of comparing different materials, and can be used as a routine test when agreed upon between the supplier and purchaser. The results of immersion tests are not intended to give any direct correlation with service conditions in view of the wide variations in temperature and special uses encountered in gasket applications. GAS PERMEABILITY DIN* Designation: 3535 This standard provides a means of measuring leakage of a gas through a gasket. This test is designed to compare the leakage rates of different products. The fluid used is nitrogen gas at an internal pressure of 580 psig (40 bar) and a gasket loading of 4,640 psi (32 N/mm 2 ). The apparatus is considerably more versatile than that used in ASTM F37. The sample gasket size can be varied; much higher internal pressures can be used. Normally measurements are made at room temperature. However, we have the ability to test at elevated temperatures. The test measures the effects on leakage rates due to changes in gasket products themselves, in gasket thicknesses, in gasket flange widths, in varying internal pressures, in varying gasket loads, and at varying temperatures. HELIUM MASS SPECTROMETER TEST The ability to control and detect leakage on an ever-decreasing scale is a requirement of industry today. Mass spectrometer technology is used where stringent leak detection is needed, such as in the manufacture of devices used in body implants, nuclear vessels and cathode ray tubes. The Helium Mass Spectrometer Leak Detector (HeMSLD) develops a high vacuum, which enables it to detect trace amounts of helium that are present. Helium gas is used as a test media in standard flange fixtures on the DIN 3535 gas permeability fixture. The HeMSLD detects the helium leakage through the gasketed joint by way of a hand-held "sniffer" probe or by a hard-piped connection from the DIN 3535 fixture or equipment where other leak detection systems are used. Leakage as low as 1 x 10-9 standard cc He/second can be detected. NOTES: * DIN Deutsches Institut für Normung e.v. 60

61 Test Procedures OTHER ASTM TESTS Purchasers may want to consider the use of the following ASTM test methods, depending on their gasketing needs: F147 - Test Methods for Flexibility of Non-Metallic Gasket Materials F607 - Test Method for Adhesion of Gasket Materials to Metal Surfaces SEALABILITY OF GASKET MATERIALS ASTM Designation: F37 Test methods A and B provide a means of evaluating fluid sealing properties at room temperature. Method A is restricted to liquid measurements and Method B (most common) can be used for both gas and liquid measurements. These test methods are suitable for evaluating the sealing characteristics of a gasket product under differing compression flange loads. Since this physical property is so important to the proper function of a gasket, it should be used as an acceptance test when test methods are agreed upon between supplier and purchaser as follows: fluid, internal pressure of fluid, and flange load on the gasket specimen. The most commonly used fluids are isooctane and nitrogen gas. Gasket load, fluid and internal pressures can vary according to customer needs. However, our experience indicates a strong preference for nitrogen gas, with a gasket load of 3,000 psi (20.7 N/mm 2 ) at an internal pressure of 30 psig (2 bar). These precise measurements of leakage rates are designed to compare gasketing products under controlled conditions. The leakage measured comes either through the gasket, or between the gasket and the flange faces, or both. Our experience over many years with thousands of test samples indicates that, in most cases, the leakage measured is a result of leakage through the gasket. It is not a question of whether or not any fibrous type gasketing product allows leakage through the gasket, but how much leakage, under any set of given conditions of time, temperature and pressure. STANDARD CLASSIFICATION FOR NON-METALLIC GASKET MATERIALS ASTM Designation: F104 This classification system provides a means for describing pertinent properties of commercial non-metallic gasket materials. Materials composed of PTFE, organic or inorganic fibers, and other fiber materials in combination with various binders or fillers are included. Materials normally classified as rubber compounds are covered in Method D2000. Since all the properties that contribute to gasket performance are not included, use of the classification system as a basis for selecting materials is limited. The purpose of the classification system is intended to provide a common language for communication between suppliers and purchasers; to guide engineers and designers in the test methods commonly used for commercially available materials, and be versatile enough to cover new materials and test methods as they are introduced. It is based on the principle that non-metallic gasket materials should be described, insofar as possible, in terms of specific physical and functional characteristics. An infinite number of such descriptions can be formulated by use of one or more standard statements based on standard tests. Tensile of Non-metallic Gasket Materials ASTM Designation: F152 The Universal Tester is used to determine the tensile strength of nonmetallic gasketing products. The types of products covered are those containing various organic fibers, inorganic fibers, flexible graphite, or fluorocarbons as described in F104. F152 is not applicable to the testing of vulcanized rubber, a method that is described in Test Method D142, nor for rubber O-rings, a method that is described in D1414. The measurement of tensile strength characterizes various classes and grades of products of a given type. It also will aid the purchaser in determining whether the gasketing product approved for a given application is being manufactured to acceptable quality. Various procedures are given for different types of materials, and in order to compare results from one lab to another, it is imperative that the applicable procedure be used. The measurement of tensile strength should not be construed as an indication of the performance of that product in use. THERMAL ANALYSIS SYSTEM Thermal Analysis, often referred to as TA, is a series of techniques that characterize materials by measuring and analyzing changes in their physical and chemical properties resulting from controlled and measured changes in temperature. The TA techniques include DSC (Differential Scanning Calorimetry), TGA (Thermal Gravimetric Analysis) and TMA (Thermal Mechanical Analysis). DSC measures heat flow into or out of a material as it is undergoing a programmed thermal profile. The resulting plot of heat flow vs. temperature can reveal a great deal of information about a material. DSC is being used to determine such things about a material as specific heat, melting point, crystallinity, glass transition temperature, degree of cure of thermosets, purity, oxidative stability, and reaction kinetics. TGA measures changes in the weight of a material. By heating a sample in a controlled manner in various atmospheres, the composition of various materials can be determined. The technique is also useful for performing thermal stability studies. TMA provides measurements of penetration, expansion, contraction, extension, and relaxation of materials as a function of either time or temperature. By using various probes and accessories, TMA can be used to determine expansion coefficients, softening points, heat deflection temperatures, viscosity, creep, and stress relaxation. 61

62 Test Procedures TORQUE RETENTION DIN This test is designed to determine the torque retention capabilities of gasketing products, when subjected to the compression load and operating temperature as defined by the test procedure. The test consists of applying a predetermined load on the test gasket via a tension screw, then heating the gasket/flange assembly to the desired temperature (there is no internal pressure). The standard test period is either sixteen (16) hours or one hundred (100) hours. At the end of the required time period, the compression load which is left acting on the test gasket is measured. This allows one to calculate the torque retention capabilities of various gasketing products. Test Equipment Quick Reference Selection Guide FOURIER TRANSFORM INFRARED SPECTROMETER (FTIR) This instrument is equipped with a number of attachments that allow scanning of liquids and solids either by transmittance or reflectance. The spectrum of the scanned sample can be compared against standard spectra contained in internal libraries within the instrument. The search program automatically finds the best match. The sample and library spectra can be displayed together on the screen for comparison. IMAGING SYSTEM System consists of a Polarized Light Microscope (PLM), Stereo Microscope, Marcro Stand, Digital Camera and Image Analysis Software. The System is useful in many areas including investigating new materials, analysis of competitive products and in failure analysis. The state of polarization of a light beam is generally modified when it is reflected or transmitted through a material. That phenomenon allows PLM to be useful in material identification and characterization, especially fibers and fillers. Magnification in excess of 400X is possible. The Stereo Microscope provides 3D images with a maximum magnification of approximately 100X. The Digital Camera / Image Analysis Software permits for achieving, manipulation and measurement of the images of interest. Stereo microscope or Dissecting microscope: Stereoscopic (3D) vision is possible by the combined action of two eyes. This requires an independent optical system for each eye (similar to how binoculars work). A stereo microscope features two tubes with independent optical systems with two eyepieces and two objectives. Which means that a stereo microscope is in fact, a combination of two compound monocular microscopes whose optical axes are at a right angle to each other and directed to the same specimen area. Stereo microscopes are used for viewing natural specimens such as minerals, insects, plant parts; they are also used for technical applications such as illuminating coins, textiles, and electronic components. Because of its long working distance, dissection and precision assembly are possible under the stereo microscope. A stereo microscope uses two different paths of light. This allows you to see a specimen in 3-D. Stereo microscopes have high depth perception but low resolution and magnification. These microscopes are great for dissecting as well as for viewing fossils and insect specimens. The best models have a built-in light source and zoom capabilities. PROGRAMMABLE, MULTI-FUNCTIONAL TEST STAND (A.S.T. Advanced Seal Tester) This highly sophisticated, PC-driven test stand evaluates properties of gasketing materials under varying conditions; it can be programmed to test leak rates from high vacuum to 300 psig internal pressure, with different compressive loads or test temperatures. Any of the parameters listed below can be programmed to ramp up while the other conditions are held constant, to study the effects these conditions have on the sealability of materials. A Helium Mass Rate Spectrometer can monitor leak rates; gasket thickness and leak rates are monitored to determine percent compression vs. load, leak rate vs. compressive stress, maximum crush resistance, and more. Programmable Parameters: Compressive load (stress) Time Temperature Internal pressure or vacuum Leak rate measurement Capabilities: Compressive load: To 107,000 lbs force (475 KN) at room temperature To 73,000 lbs force (325 KN) at 570 F (300 C) Temperature: to 840 F (450 C) Gasket thickness: 0-5/16" (0-8mm) Internal pressure: High vacuum (10-3 mbar) to 300 psig He (20 bar) Helium leak rate measurement: 1 standard cc/ second down to 1 x standard cc/ second 62

Void content and flexibility will affect all aspects of a diaphragm leakage, cycle life, reliability, downtime, etc. Flex Cycle, Millions M 6.5M Increased flexibility The ability to flex back and forth without deformation is one of the key features of a diaphragm. The greater the flexibility of a diaphragm, the longer it s life will be. 2 0 Conventional Skived PTFE Modified Skived PTFE T x ½ W x 6 L Specimen GYLON 3522 A longer diaphragm life means more uptime, improved equipment reliability, decreased labor and protection of downstream equipment. The MIT Flex Endurance test simulates the bending forces a diaphragm sees in an actual application. Compared to Conventional and modified skived PTFE, GYLON 3522 lasts about 3 times longer.

65 Garlock Diaphragm: Materials and Technical Capabilities Reduced void content Void content measures the potential for permeation through the material; the denser the polymer structure, the fewer voids there will be in the material. As void content decreases there will be less permeation which reduces the risk of cross-contamination and increases the life of the material. Lower void content also results in less deformation of the material. The Stretch Void Index measures the % void content after the material has been flexed. Compared to both conventional grade and modified grade skived PTFE, GYLON Diaphragm Style 3522 has a lower void content at <1%. % Void Content ASTM D4895: Stretch Void Index (1/16 thk) Case History In a popular mechanically actuated pump, GYLON PTFE Diaphragm lasted 8 times longer than the competitive modified skived PTFE.

93 Garlock ONE-UP Diaphragms YAMADA DIAPHRAGM DESIGN All Yamada original equipment diaphragms are 100% PTFE and are retained inside the pump using a metal retaining ring. Garlock has designed ONE-UP diaphragms for Yamada pumps using the flange/bolt sealing design and elastomer backing for longer service life/performance. We also offer 100% PTFE ONE-UP diaphragms for customers unable to utilize an elastomer-backed diaphragm, typically for high purity applications. 100% PTFE diaphragms are available for all Yamada NDP and DP series pumps. Elastomer-backed/flange bolt-designed ONE-UP diaphragms will only fit the new NDP series pumps. INTERCHANGEABILITY Iwaki, Iwata, Hethon, Graymills, Johnson.
